Verdict
The clearest difference is in-app purchases: LIBCORN at none against World Time Clock's 1. LIBCORN also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.1). World Time Clock's advantage is update cadence (every 2 weeks vs every 17 months). On price and device support there is nothing between them.
